		<div slot="explanation">
			<a href="https://tonejs.github.io/docs/FatOscillator">Tone.FatOscillator</a> creates multiple oscillators
			and detunes them slightly from each other to thicken the sound. The <code>count</code> parameter sets 
			the number of oscillators and <code>spread</code> sets the total spread (in cents) between the oscillators. 
			<br><br>
			FatOscillator is also available in <a href="https://tonejs.github.io/docs/OmniOscillator">Tone.OmniOscillator</a> 
			by prefixing another type with "fat", then use the count and spread to control the number and detune of the oscillators. To create a "supersaw": <code>omniOscillator.type = "fatsawtooth"</code>.
